[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 =-e`OHA  
qQu}4Ye>  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： {T^"`%[   
enableservice('AutomationServer', true) .m]"lH*  
enableservice('AutomationServer') Az}.Z'LJ  
kIlc$:K^  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 j<-#a^jb

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： +;P8QZK6  
1. 在FRED脚本编辑界面找到参考. ;p!|E3o.  
2. 找到Matlab Automation Server Type Library

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 PE~umY]

1. 创建Matlab服务器。 ?+]prbt)  
2. 移动探测面对于前一聚焦面的位置。 !y&uK&1  
3. 在探测面追迹光线 K/,y"DUN&  
4. 在探测面计算照度 rff=ud>Jf  
5. 使用PutWorkspaceData发送照度数据到Matlab a5/6DK>  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6V"|  
7. 用Matlab画出照度数据 ]ZD W+<  
8. 在Matlab计算照度平均值 LyaFWx  
9. 返回数据到FRED中 :ub 4p4h*
